Abstract
We present a theoretical study of the quantum confinement of the two-dimensional electron gas (2DEG) in a group-III-nitride-based single heterostructure under uniformly doping, taking into account effects arising from polarization charges and ionized dopants. By using an extended Fang-Howard wave function for the actual model of a finitely-deep triangular quantum well, we are able to derive an analytic expression for the self-consistent Hartree potential due to uniformly doping. We proved with the presence of the sheet polarization charges, electron wave function is been squeezed close to the barrier. We studied the effect of polarization charges on the quantum lifetime of the 2DEG.
